About This Acura RSX Base 2005 Build
We love featuring real builds from real owners. This Acura RSX Base 2005 sits on a set of 17×9 / 17×9-inch Cosmis Racing XT-206R wheels, and the result speaks for itself.
The owner chose Cosmis Racing for a reason. This brand delivers serious quality and a design language that turns heads at every car meet. We see hundreds of Acura RSX Base builds come through WheelFront every month, but this one stands out. The combination of the exterior with the Cosmis Racing XT-206R creates a look that balances aggression with elegance.
Fitment Breakdown: Cosmis Racing XT-206R on the Acura RSX Base 2005
I walked up to this RSX and immediately noticed the aggressive stance. Throwing 17x9 wheels on a base model changes the entire personality of the car. We usually see these cars running skinny stock wheels, so this jump to width makes a massive difference.
The choice of a +5 offset on these Cosmis XT-206R rollers is wild. This puts the wheels way out toward the fender edges. You get that meaty, wide-body look without actually cutting the sheet metal. It completely transforms the track width of the chassis.
Clearance is the first thing I checked when I saw the car parked. Those massive spokes clear the stock calipers with room to spare. We love how the barrel design creates a deep, aggressive lip that screams performance. It gives the RSX a much more muscular profile than factory specs ever allowed.
You need to talk about the hub bore to get this right. The RSX uses a 64.1mm hub, and you better have high-quality hub-centric rings. Without them, you will deal with highway vibrations that drive you crazy. Trust me, do not skip that step.
The coilovers make this fitment possible, but they create their own set of challenges. By lowering the center of gravity, you change the camber curve of the suspension. We noticed a decent amount of negative camber to tuck these wheels under the fenders. It looks intentional rather than accidental.
Watch out for the fender liners if you daily drive this setup. With a +5 offset, you will rub the plastic tabs on hard corners. We suggest a clean roll on the fender lips to keep your tires from shredding. It is a small price to pay for this level of aggression.
What We Recommend for Acura RSX Base 2005 Owners
If you want to replicate this look, start with the right mindset. You need a stiff set of coilovers to stop the tires from kissing the fenders. Factory struts just won't hold these wheels in place during a spirited drive.
Most owners should aim for 17x8 or 17x9 wheels. Anything wider than 9 inches requires serious body work that goes beyond simple rolling. Keep your offset between +20 and +35 if you want to avoid the headache of excessive rubbing.
We see too many people run mismatched tire sizes on these cars. Stick to a square setup with 235/40 or 245/40 tires for the best handling balance. This keeps the understeer in check and makes the car feel predictable through the twisties.
Do not go crazy with wheel spacers unless you have to. If you choose the correct offset from the start, spacers are just extra parts that can fail. We prefer a direct bolt-on setup that keeps the wheel bearing load where it belongs.
Finally, check your alignment specs once the wheels are on. You need at least -2 degrees of camber up front to pull off this flush look. Without that, the wheels will poke too far and look like a cartoon character. Get it aligned by someone who understands modified car geometry.
Style and Build Analysis
The Gunmetal finish on these XT-206R wheels is a stroke of genius. It creates a subtle, industrial contrast against the stock paint. It looks refined but maintains an underlying hint of pure aggression.
The six-spoke design is a classic choice that fits the RSX body lines perfectly. These wheels look like they belong on a time-attack track rather than a grocery store parking lot. The proportions are dead on, filling the wheel wells with authority.
Most builds we see try to go too flashy with chrome or neon colors. This Gunmetal choice keeps the car looking clean and professional. It lets the shape of the wheel do the talking instead of relying on cheap visual gimmicks.
I love how the light plays off the concave face of these wheels. As you walk around the car, the shadows shift and highlight the deep barrel depth. It gives the RSX a sense of motion even when it sits perfectly still.
This car feels like a cohesive package rather than a collection of random parts. The wheels complement the lowered height without making the car look like a toy. It is a textbook example of how to build a street-ready RSX that stands out in a crowd.
Why We Love This Build
This RSX captures everything I love about the car scene. The way those Gunmetal Cosmis wheels catch the afternoon sun makes the whole build pop. It sits low, looks fast, and commands respect the second you pull into a meet.
We often see people overthink their mods, but this setup works because it is simple and bold. The wheels fill the arches perfectly, giving the car a planted, grounded stance. It is a reminder that the right set of wheels changes a car from basic to legendary.
This build stops me in my tracks because it is pure function meeting aggressive style. It inspires us to get back in the garage and tighten our own bolts. Go get yourself a set of these and change your game.

Before You Buy: Fitment Checklist
We talk to Acura RSX Base owners every day. These are the questions we hear most before they pull the trigger on new wheels.
Will 17×9 / 17×9-inch wheels fit my Acura RSX Base? Yes, but fitment depends on width, offset, and tire size working together. A wrong offset means rubbing. A wrong tire size means poor handling. Always verify all three.
Do I need to modify my fenders? That depends on your offset and suspension. A conservative offset with stock ride height usually fits without modification. Go aggressive and you may need to roll or pull your fenders.
Can I daily-drive this setup? Absolutely. Thousands of Acura RSX Base owners run 17×9 / 17×9-inch wheels every day. The key is choosing the right tire with enough sidewall to absorb road imperfections.
